Hi,

I have done a rebuild by Oppliger Motorsport, 582hp @ 1.75bar of boost with E85 fuel (105ron). No problem there as its a beast.

The car performs very good once it is hot and running, but now when temperatures drop below 10-15degrees outside it doesn't want to start at all.

Plugs are IK31.

Romain Oppliger came from Italy to Belgium to fix coldstart problems and it was OK untill now its 5degrees and i tried to start it after 1 week and it doesn't want to go again.

Keeps cranking and you hear it WANTS ignition but after 10x i stopped..
The problem could be the plugs as they are "cold", but i want a 500+ engine that i can drive ANY DAY of the year and not only when its 20degrees outside.
I also tried cranking with the injector plugs removed because it maybe overfueled or somekind.. But no succes.

Anybody got another idea?
